Returns the sum of the powers of all the numbers from start to end (both inclusive).

• Use range() in combination with a list comprehension to create a list of elements in the desired range raised to the given power.
• Use sum() to add the values together.
• Omit the second argument, power, to use a default power of 2.
• Omit the third argument, start, to use a default starting value of 1.

def sum_of_powers(end, power = 2, start = 1):
  return sum([(i) ** power for i in range(start, end + 1)])

sum_of_powers(10) # 385
